When installing your 

MagnuM Winchester (WIN) Corn/Biomass/Wood Pellet

 stove, particular attention 

needs to be made in regards to fire protection.  If the unit is not properly installed, a house fire may result.  
For your safety, follow the installation and operation instructions provided, and if a question arises contact 
local building or fire officials about restrictions and installation requirements in your area. 

9

 

Read the operations and fuel section of this manual before plugging in your unit. 

9

 

Always unplug the unit before attempting any service work. 

9

 

Do not connect the unit to a chimney flue already serving another appliance. 

9

 

When installing the chimney pipe to the unit, it is important to remember that the unit operates on a 
negative pressure and the chimney on a positive pressure.  All chimney connections, elbows and fittings 
must be airtight.  

(Proper venting practices must be followed. Consult with a venting professional)

 

9

 

Ashes must be disposed of in a metal container with a tight fitting lid. 

9

 

All minimum clearances to combustibles must be followed. 

9

 

The 

MagnuM Corn/Biomass/Wood Pellet Stove 

is tested for operation with wood pellets, with an ash 

content of no more than 2% and Corn with a moisture content from 10-14 percent.  

It is recommended 

that wood pellets with an ash content of 1% or less be used for efficient operation of this unit. Higher 
ash content fuels will require additional maintenance and service.  Also, for use with wood pellets, 
cherry pits, olive pits or other pelletized Biomass fuel. Corn with 11-12 percent moisture is ideal.  

9

 

It is important to use fuel that is clean, dry and consistent.  

Make sure that your supplier is giving you 

the same fuel each time that you purchase.  It is recommended that you purchase your entire heating season 
supply of fuel at one time so that the fuel will be the same.

 

9

 

A voltage surge protector or ground fault outlet is required for this unit.  The electrical component 
warranty will be voided if surge protection is not installed before operating this unit.   

9

 

A grounded outlet must be provided with proper polarity.  A constant 120 volt (12volt on DC 
models), 60 cycles must be provided for proper operation or the warranty of this appliance will be 
forfeited.  

9

 

Special attention needs to be taken to clean out the top heat exchangers of this unit on a regular 
basis.  The fly ash settles on the heat exchangers and must be cleaned off to keep the unit operating 
properly.  Check for plugging every two-four weeks or when needed. 

9

 

If unit is not operated for extended periods of time (like summer) unplug the unit and disconnect the 
battery to assure long life of electrical components.
